I do cryptograms at www.cryptograms.org. One that stumped me badly for a long time:

FQUTZ HGBEH KTMU NWEEH; CUUVEU GDUH KTMU GDEJ NWHKUH.

I ended up pulling a dictionary text file and created a searchable dictionary of word patterns. Not the fastest way to figure it out, but hopefully applicable to future ones. Eventually I'd love to write a program that can solve simple substitution ciphers based on the English language (and in the future plug in other language dictionaries, but step by step).

In the meantime, I keep my 100% completion rate on the month, even though it is at the cost of my solving time.
